基于电话网络的办公楼防火防盗报警系统设计与实现

Design and Realization of the Fireproof and Theft-proof Alarm System Based on Phone Network

本文探讨了一种适合于办公楼的防火防盗报警系统,该系统采用上下位机通信工作方式,具有振铃检测、模拟摘机、信号音检测、警情检测功能。系统的下位机检测警情信号后,摘机拨打上位机电话,并利用DTMF编码将警情和地址信息发送到上位机,使警情得以及时、有效处理,该系统具有广阔的市场空间和良好的应用前景。

This paper discusses a fire alarm system suitable for office buildings.The system uses upper and lower computer communications to work,having functions such as ringing detection,extraction simulation machine,sound signal detection and police intelligence detection.After detecting the signals of police intelligence,the lower computer of the system will make a call to the upper computer,and use DTMF codes to send the police information and address information to the upper computer, which makes the police information processed timely and effectively.The system has a vast market space and a good prospect.
